IMPROVEMENT` IN STEAM WATER-ELEVATORS.

Specification forming part of Letters Patent No. 133,749, dated December l0, 1872; antedated December 4,

To all lwhom it 'may concern:

Beit known that I, WILLIAM BURnoN, of Brooklyn, in the county of 'Kings and State of New York, have invented a new and useful Improvement in Apparatus for Raising and ForcingVVater by the Condensation and Pressthe following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of this specitication. f

This invention relates to apparatus for raising and forcing water of that class in which a vacuum is formed in two adjacent chambers alternately by the condensation of steam therein, and water raised into them by atmospheric pressure is afterward expelled by the pressure of steam, which is subsequently condensed to The imprqvement consists in the combination, with the chambers and their steam-inlet pipes, and pipes forming a communication between the lower part of one chamber and the upper part of the other, of a valve, having a swingby, on the Vlling of one chamber and adjacent' inlet-pipe and a slight reduction of pressure in the other, the valve is shifted so as to reverse the supply of steam from one to th other.

The accompanying drawingv represents a central vertical section of an apparatus constructed according to my invention.

A Aare the two main chambers of the apparatus. They are represented as being ar`v ranged side by side, but may be arranged in any lother convenient relation to each other, and maybe of any suitable form. They communicate with av suction-pipe, B, throughvalves C C, and are provided with discharge- 'pipes D D, furnished at some distance from their communication with valves E E. F is the steam-valve box, made of upwardly-flaring form' and iattened transversely by two branch pipes, Gr' G, that connect its opposite sides with the chambers A A. The box Fis intended to receive steam above the valve through a pipe connecting it with a boiler. The valve I consists of a dat disk or plate h aving its tom of the valve-box, that it may swing or vi-A brate between the ends of the inlet-pipes G G,

and so shut off communication between one or the other and theinterior of the valve-box.

The ends of the inlet-pipes slightly project into the valve-box to form narrow annular` seats for the valves, either of such seats being surrounded by live steam from the boiler when the valve closes against it, and thereby havingrthe pressure of steam on the other side partly counterbalanced. H H are pipes which lead each from the lower part of one chamber to the Aupper part of the other, and are provided with check-valves ff capable of opening only toward their upper ends.

To start the apparatus, the chambers A A are first lled with water, either by pourin git in through openings, which are afterward closed, or by shifting the steam valve by suitable hand-gear, and so admitting steam to them, and allowing it to condense and form vacuums, into which water will ow by atmospheric pressure. The valve is then brought by the hand-gear to a position to shut off steam from one pipe, G, and admit it to the other and to its chamber A. I will suppose, for example, that the steam is admitted to the right chamber, from which by its pressure it forces the water through the discharge-pipe D, but at the same time forces some into the left chamber, throughthe pipe H leading into the upper part of the latter, and so fills the inlet-pipe G of the latter. The pressure is now nearly equal on both sides of the valve, until, on the completion of the discharge of the right chamber, the water in its dischargepipe D falls back and condenses a portion of the steam in the said chamber, and effects a slight reduction of pressure in it and on .the right side of the valve, thereby enabling the pressure of water on its left side to throw it over against the right pipeG, and 'thereby shut off the supply of steam from the right chamber and admit it to the left. The flowing of water into the right chamber from the pipe H, leading into the upper part thereof, completes the condensation of steam in said l into the chamber, and, by condensing a portion of the steam therein, causes a reduction of pressure on the left side of the valve, and so enables the Water on its right side to push it over toward the left, shutting off the supply of steam from the left chamber and aga-in admitting it to the right. Water iiowiug from the right chamber into the left through the proper pipe H completes the condensation of the steam in the latter chamber, and, by forming a vacuum therein, causes it to be lled with Water by atmospheric pressure While theother chamber discharges. Thus the operation is kept up, each chamber alternatelyr filling and discharging simultaneously with the discharging and illing of the other.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the chambers A A, valve-box F, inlet-pipes G G, and pipes H H of the swinging valve I, arranged, substantially as herein described, for operation as herea in set forth.
